HS-LS2-2 Use mathematical representations
to support & revise explanations based on evidence about factors
affecting biodiversity & populations in ecosystems of different scales.

Science & Engineering
Practices:

5. Using Mathematics & Computational
Thinking

Disciplinary Core Idea Progressions:

DCI

Grades: 9-12

LS2.A Interdependent relationships in
ecosystems

Support & revising explanations
about factors affecting populations in ecosystems.

LS2.C Ecosystem dynamics,
functioning, and resilience

Computationally modeling how factors
can affect the carrying capacity of ecosystems at different
scales. Evaluating claims & evidence that ecosystems
maintain relative homeostasis, but can be altered as the result
of changing conditions.

CCC scale/prop

2015High School Life Science Standard (Grades 9-12)

HS-LS2-6 Evaluate the claims, evidence, &
reasoning that the complex interactions in ecosystems maintain
relatively consistent numbers & types of organisms in stable but
moderate to extreme fluctuations in conditions may result in a new
ecosystem.

Science & Engineering

LS2.D Social interactions and group
behavior

Examining evidence of group behavior
& its influence on survival & reproduction.

CCC cause/effect

2015High School Life Science Standard
(Grades 9-12)

HS-LS4-2 Construct an explanation based on
evidence that the process of evolution primarily results from four
factors: (1) the potential for a species to increase in number, (2) the
heritable genetic variation of individuals in a species due to mutation
and sexual reproduction, (3) competition for limited resources, and (4)
the proliferation of those organisms that are better able to survive and
reproduce in the environment.

Science & Engineering Practices:

6. Constructing explanations & Designing Solutions

Disciplinary Core Idea Progressions:

DCI

Grades: 9-12

LS4.B Natural Selection

Providing evidence of
evolution & the factors that drive this process. Using
statistical data to explain how organisms with an advantageous &
inheritable trait tend to increase in proportion to organisms
lacking this trait.

LS4.C Adaptation

Using statistical evidence &
probability to explain the variation, distribution, & expression
of traits over time in a population. Providing evidence of
the factors that drive this process, & how natural selection &
changing environments lead to the adaptation, emergence, &
extinction of populations.

CCC cause/effect

2015High School Life Science Standard
(Grades 9-12)

HS-LS4-3 Apply concepts of statistics and
probability to support explanations that organisms with an advantageous
heritable trait tend to increase in proportion to organisms lacking this
trait.

Science & Engineering Practices:
4. Analyzing and Interpreting Data

Disciplinary Core Idea Progressions:

DCI

Grades: 9-12

LS4.B Natural Selection

Providing evidence of
evolution and the factors that drive this process. Using
statistical data to explain how organisms with an advantageous
and inheritable trait tend to increase in proportion to
organisms lacking this trait.

LS4.C Adaptation

Using statistical evidence and
probability to explain the variation, distribution, and
expression of traits over time in a population. Providing
evidence of the factors that drive this process, and how natural
selection and changing environments lead to the adaptation,
emergence, and extinction of populations.

CCC patterns

2015High School Life Science Standard (Grades 9-12)

HS-LS4-5 Evaluate the evidence supporting
claims that changes in environmental conditions may result in: (1)
increases in the number of individuals of some species, (2) the
emergence of new species over time, and (3) the extinction of other
species.
